AI agent commerce: buy gift cards, top up phones, and get travel eSIMs with Bitcoin, ETH, SOL, USDC, USDT, Litecoin, Dogecoin, and 15+ cryptos on
Connect Agents to Claude, Cursor or any other MCP client and it stops being a tab you switch to. AI agent commerce: buy gift cards, top up phones, and get travel eSIMs with Bitcoin, ETH, SOL, USDC, USDT, Litecoin, Dogecoin, and 15+ cryptos on Solana, Ethereum, Base, Polygon, Arbitrum, Tron, and more. **No account, no CLI install, no. The agents mcp server is what makes that connection.
Installation goes through your MCP client rather than a global install: point it at skills on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
Skills — 3 (cryptorefills-catalog, cryptorefills-buy, cryptorefills-x402)Brands — 10,500+Countries — 180+Languages — 10Setup — Zero — no account, no npm install, no API keySpec — Agent SkillsSkill — Descriptioncryptorefills-catalog — Search and explore 10,500+ gift cards, mobile top-ups, and eSIMs across 180+ countries via MCP.

Nocryptorefills-x402 — Autonomous agent commerce via x402 protocol. Two settlement rails: USDC on Base (EIP-3009) or USDC SPL on Solana mainnetThis sits in the payments and commerce group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. Agents's toolset — Skills, Brands, Countries and 7 more — is a fair guide to whether it matches your workflow. It is maintained by cryptorefills; worth a glance at recent repository activity before you build anything load-bearing on it.
SyncDev reviews every entry in this directory against the project's own documentation before publishing, and revisits them as servers change.
